If you have an easy out, (a reverse threaded tapered tool) you can insert it into the threads and turn them counterclockwise and they will unthread. If you don't try this. This is a very delicate manuver, but here goes. I always remove the spout so I can work on it off the faucet, (this also allows me to purchase a new one if i screw up the old one). Then I take a jewlers screw driver and slowly peal the male threads into the center of the opening, always pushing away from the female threads so I don't damage them. You should use a magnifying glass so you can see the seperation of the two threads. Find the largest opening and wiggle the screwdriver back and forth till you get them out. Basicly you are colapsing the brass into the center.

By the way, kitchen sink faucets aren't that expensive and are very easy to install, right now might just be the perfect time to install the one you always wanted to get.

While changing an old aerator in our guest bathroom it broke off leaving the threaded part in the faucet.

How do I remove the broken threaded part so I can put in a new aerator?

Ray VinZant gave a great answer in this thread......

....for your bathroom sink you MAY need to remove the entire faucet to see/work on it.......

"...measure once.....cut twice....throw that one away and cut a new one...."
